roughly two-thirds of global sea-level rise; the remaining third is primarily due to the warming of the oceans, which causes seawater to expand. Accordingly, the development of our planet’s ice sheets and glaciers [...] and that ice-loss processes have been set in motion that will have lasting consequences. In the Arctic, temperatures are rising twice as quickly as the global average; as a result, the Greenland ice sheet’s

reflect in detail processes in the ocean, which have a major influence on the climate. In response, the AWI has developed a special ocean model (FESOM), which simulates e.g. ocean currents and sea ice. For their [...] All around the world, there are natural climate archives – the sediments on the ocean floor, ancient ice in the Arctic and Antarctic, wood for tree-ring analyses, and more. These archives contain what [...] computer programmes used to simulate reality: the motion of air masses, radiation from the sun, and ocean currents – they’re all climate-relevant processes that, with the aid of mathematical formulas, can

affecting fishing in the Southern Ocean? To FAQ element How can fish survive in the frigid waters of the Southern Ocean? Due to its high salinity, the Southern Ocean’s water doesn’t freeze at zero degrees [...] Southern Ocean. In winter, sea ice up to 1.5 metres thick forms atop the water. Air temperatures over the sea ice can easily reach minus 30 degrees Celsius. Given its high salinity, the ocean’s water only [...] ice? Similar to the Arctic, the Antarctic is home to numerous species that have adapted to life in, on or below the ice. For example, of the six seal species native to the Southern Ocean, only the Antarctic
